Work Aptitude question

1 women=1/15
1 men = 110
if both men and women works together they will complete the work by 6 days
=(1/10)+(1/15)
=(15+10)/150
=25/150
=1/6 (i.e)
6 days

3/20

6 days is the right answer.

6.5

Let work=1
work done by 10 men in 15 days=1
So
Work done by 10 men in 1 day=1/15
Similarly
Work done by 15 women in 1 day=1/12

work done by 10 men + 15 women in 1 day=1/15+1/12=9/60

So time taken to complete work = 60/9 days = 6.67 days

1 women=1/15
1 men = 1/10
if both men and women works together they will complete in..
=(1/10)+(1/15)
=(2+3)/30
=5/30
=1/6
so they will take 6 days to complete the work

10 men=12
15 woman=15
so 10*15=150
10+15=25
therefore 150/25=6
answer=6 days

6 days is wrong answer....

let the amount of work be done = i
work done by men in one day = i/15
work done by women in one day = i/12
now, if they together take " x " days to complete the required " i " amount of work..., the equation goes as

work done together in one day*no. of days required = " i " amount of work.....

(i/15 + i/12)x = i ...... solving for x gives 20/3.... that is required no. of days :)
